Saint John the Chozebite, Bishop of Caesarea in Palestine (587-596), was famed for his struggle against the Eutychian heresy, and also for his grace-filled gifts of discernment and wonderworking. He was born in the Egyptian city of Thebes and while still a youth he spent a long time with his uncle, an ascetic, in the Thebaid wilderness.
The emperor, who learned of John’s holy life, decided to make him bishop of the city of Caesarea. But the saint, yearning for solitude, withdrew into the Chozeba wilderness (between Jerusalem and Jericho) and pursued asceticism there until the end of his life.
Whenever he served the Divine Liturgy, he saw a heavenly light in the altar.
